and tools for Microsoft SQL Server. Blog 23/01 Identifying the source of SQL Server login failures (18456 errors) Tags: 18456, Default trace, Login failures, NT AUTHORITYANONYMOUS LOGON, SQL Profiler Share: Tweet We’ve all had to http://www.eraofdata.com/sql-18456-login-failures isolate the source of login failures (SQL Server 18456 errors) from time to time, http://www.isunshare.com/sql-server/fix-sql-server-failed-login-error.html and thanks to older versions of SQL Server not presenting enough data in the error log about these login failures it’s not as straightforward as it could be. However, with a little help from SQL Server’s tracing tools it’s not too difficult to get to the bottom of these login failures. The technique is pretty much version independent, error 18456 but I will assume you know how to use SQL Server Profiler and capture a trace. 18456 errors A login failure will throw an 18456 error and will be accompanied by the following entry in the SQL Server error log (SQL Server 2000 does not display the IP address): 2009-01-15 09:40:24.55 Logon Error: 18456, Severity: 14, State: 8. 2009-01-15 09:40:24.55 Logon Login failed for user 'DomainUser'. [CLIENT: xxx.xxx.xxx.xxx] The severity of the error error 18456 sql indicates the seriousness of the error. A severity level of 14 indicates an error in the range described as user correctable, which is understandable for login failures. The next item of information the error provides is the state number. Most errors have a state number associated with them which provides further information which is usually unique to the error that has been thrown. For a login error, state: 8, shown in the above example, indicates an invalid password was used. The state number therefore provides invaluable information about the reason for the login failure and can often be enough to identify the cause of an 18456 error. The table below illustrates what some of these state values mean: State Description 1 Account is locked out 2 User id is not valid 3-4 Undocumented 5 Login not found; sometimes a connecting application is incorrectly set to specify connection via SQL Authentication for a Windows account 6 Undocumented 7 The login being used is disabled 8 Incorrect password 9 Invalid password 10 Related to a SQL login being bound to Windows domain password policy enforcement.
